Better sorting of waste streams is the be-all and end-all. Packaging could then be turned into new plastic raw material. Researchers are working intensively on chemical or biotechnological processes for plastic recycling. However, most of them are not yet suitable for industrial use.<\/p>\n<p>In principle, the aim of chemical recycling processes is to remove the material from <strong>Plastic packaging<\/strong> into original components such as polypropylene or polyethylene. With the \u201e<strong>Monomers<\/strong>\u201c new plastics can be produced again.<\/p>\n<p>These processes can also be used to \u201e<strong>Plastic-rich waste streams<\/strong>\u201c that conventional mechanical recycling methods fail to process. That said <strong>Rainer Mantel<\/strong>, Managing Director of BKV GmbH, in March at the specialised press day of <strong>Plastics Europe Germany<\/strong>. He presented a study on chemical recycling processes. Mantel emphasised that chemical recycling is merely a building block for closing the carbon cycle.<\/p><div class=\"packa-in-post-alle\" style=\"text-align: center;\" id=\"packa-3558003948\"><div id=\"packa-1088679431\"><a data-no-instant=\"1\" href=\"https:\/\/packaging-journal.de\/en\/newsletter\/\" rel=\"noopener\" class=\"a2t-link\" target=\"_blank\" aria-label=\"PJ Self-promotion English 03\"><!--noptimize--><img src=\"https:\/\/packaging-journal.de\/wp-content\/uploads\/2026\/01\/PJ-Eigenwerbung-English-03.png\" alt=\"\"  srcset=\"https:\/\/packaging-journal.de\/wp-content\/uploads\/2026\/01\/PJ-Eigenwerbung-English-03.png 840w, https:\/\/packaging-journal.de\/wp-content\/uploads\/2026\/01\/PJ-Eigenwerbung-English-03-300x75.png 300w, https:\/\/packaging-journal.de\/wp-content\/uploads\/2026\/01\/PJ-Eigenwerbung-English-03-768x192.png 768w, https:\/\/packaging-journal.de\/wp-content\/uploads\/2026\/01\/PJ-Eigenwerbung-English-03-18x5.png 18w, https:\/\/packaging-journal.de\/wp-content\/uploads\/2026\/01\/PJ-Eigenwerbung-English-03-332x83.png 332w, https:\/\/packaging-journal.de\/wp-content\/uploads\/2026\/01\/PJ-Eigenwerbung-English-03-664x166.png 664w, https:\/\/packaging-journal.de\/wp-content\/uploads\/2026\/01\/PJ-Eigenwerbung-English-03-688x172.png 688w\" sizes=\"(max-width: 840px) 100vw, 840px\" width=\"840\" height=\"210\"  style=\" max-width: 100%; height: auto;\" \/><!--\/noptimize--><\/a><\/div><\/div>\n<h2>Chemical plastics recycling to become suitable for industrial use<\/h2>\n<p>However, many processes are still many years away from industrial suitability, said Mantel.
